Specific details for implementing the invention

[0017] To make the purpose, technical solution, and advantages of the embodiments of the present invention clearer, the present invention will be described in more detail below in conjunction with the drawings. In general, the components of the embodiments of the present invention described and illustrated in the drawings attached herein may be arranged and designed in various configurations.

[0018] Hereinafter, some embodiments of the present invention will be described in detail in conjunction with the attached drawings. The features of the following embodiments may be combined with one another without contradiction.

[0019] [Massage device]

[0020] Combining FIGS. 1 to 3, in one embodiment, the massage device of the present application comprises a top case (1), an under case (2), a soft cloth (3), a band (4), and a massage movement (5). The massage device of the present embodiment can be used to massage a user's limbs. The top case (1) is equipped with a display and operation buttons, the under case (2) is connected to the top case (1), the soft cloth (3) is mounted on the under case (2), the band (4) is mounted between the top case (1) and the under case (2), the band (4) may be an elastic band, and a claw is attached thereto. In the drawings, only a part of the structure of the band (4) is shown. The massage movement (5) is mounted to the top case (1) through a screw post. When the massage movement (5) operates, it provides a massage to the user through the soft cloth (3). The soft cloth (3) can also be replaced with a part made of a soft rubber material, such as silicone, and can be waterproof.

[0021] [Massage Movement]

[0022] Combining FIGS. 4 to 14, the massage movement (5) of the embodiment of the present application date includes a base (5A), a swing arm (5B), a first massage head (5C), a center base (5D), a swing frequency control member (5E), a swing width control member (5F), a limiting member (5G), a swing frequency driving motor (5H), a swing width driving motor (5I), a swing frequency power transmission mechanism (5J), a swing width power transmission mechanism (5K), an eccentric lever (5L), a transfer base (5M), and a position sensing mechanism (5N). The swing arm (5B), the first massage head (5C), and the center base (5D) are a plurality of corresponding groups.

[0023] The base (5A) is used to mount other parts of the massage movement (5), and the base (5A) has a semicircular receiving groove corresponding to the swing frequency drive motor (5H) and the swing width drive motor (5I), and a sliding groove (K) that allows the center base (5D) to slide.

[0024] The swing arm (5B) is a long rod structure, and a long hole groove (5B-1) is opened along the length direction of the swing arm (5B).

[0025] The first massage head (5C) is mounted on the swing arm (5B), and the first massage head (5C) may be a massage head having heating and light-emitting functions. The number of first massage heads (5C) on each swing arm (5B) can be adjusted according to the needs of the product design.

[0026] The central base (5D) is provided with a base portion (5D1) and a sliding joint portion (5D2), and the sliding joint portion (5D2) is located on the upper part of the base portion (5D1). The base portion (5D1) is located within a sliding groove (K) to limit the central base (5D) to move within a set range. The sliding joint portion (5D2) is slidably coupled with the swing arm (5B) by passing through the long hole groove (5B-1) of the swing arm (5B), and the sliding joint portion (5D2) is located between the outer end (K2) and the inner end (K1) of the swing arm (5B), allowing the swing arm (5B) to rotate around itself. By adjusting the position of the base part (5D1) within the sliding groove (K), the relative positions of the sliding coupling part (5D2) and the inner end (K1) and outer end (K2) of the swing arm (5B) can be adjusted, thereby controlling the swing width of the outer end (K2) of the swing arm.

[0027] The swing frequency control member (5E) is mounted on the base (5A) via a T-shaped pin member (T1) and rotates around a first set center axis. In this embodiment, the inner ends (K1) of a plurality of swing arms (5B) are installed spaced apart along the outer circumference (5M-1) of the transfer base (5M) and are all rotatably connected to the transfer base (5M) (rotatably connected via an I-shaped pin member (T2) as shown in FIG. 9), and the transfer base (5M) is rotatably connected to the swing frequency control member (5E). Specifically, the transfer base (5M) is rotatably sleeved to the eccentric lever (5L), and the eccentric lever (5L) is eccentrically installed on the swing frequency control member (5E) (although this embodiment is molded as a single unit, it can also be installed as a separate unit). A cover (5O) is installed at the end of the eccentric lever (5L) to restrict the transfer base (5M) from detaching from the swing frequency control member (5E). The cover (5O) is held to the eccentric lever (5L) by a fastening screw (5P), and the rotational center axis of the transfer base (5M) is eccentrically installed with respect to the first set center axis. Since the transfer base (5M) can rotate relative to the swing frequency control member (5E) and the swing arm (5B) can rotate relative to the transfer base (5M), when the swing frequency control member (5E) rotates, each swing arm (5B) does not get stuck. A second massage head (not shown) is installed on the transfer base (5M) to further expand the massage range and massage technique of the massage movement. In combination with FIG. 16, to make the massage area more omnidirectional, in another embodiment, a second massage head (5Q) may be installed on the cover (5O), and the cover (5O) may be designed as part of the second massage head (5Q), for example, as the base of the second massage head (5Q). However, it should be understood that the second massage head (5Q) may also be installed on the transfer base (5M) or the eccentric lever (5L).

[0028] The swing width control member (5F) rotates around a second set center axis, and in this embodiment, the swing width control member (5F) is sleeved to the swing frequency control member (5E), and the rotation center axes of the swing width control member (5F) and the swing frequency control member (5E) overlap (i.e., the first set center axis and the second set center axis overlap). It should be understood that in other embodiments, the first set center axis and the second set center axis may be designed to be parallel to each other and spaced apart at a constant distance, or the two center axes may be designed to form a constant angle. The swing width control member (5F) can convert its rotational motion into a movement motion of the center base (5D) within a set range. Specifically, the swing width control member (5F) of the present embodiment is provided with a guide sliding groove (S) that is slidably coupled with the sliding coupling part (5D2) of the center base (5D). The number of guide sliding grooves (S) corresponds to the number of center bases (5D). The expansion direction of the guide sliding groove (S) and the movement direction of the center base (5D) form a set angle (see FIG. 11 for the shape and trajectory of the guide sliding groove (S). The angle allows the guide sliding groove (S) to push the sliding coupling part (5D2) when the swing width control member (5F) rotates, thereby enabling the center base (5D) to move within a set range. In this embodiment, the swing width control member (5F) has an inner circumference (N1) and an outer circumference (N2), a guide sliding groove (S) is installed in the outer circumference (N2), the inner circumference (N1) is recessed relative to the outer circumference (N2), the inner circumference (N1) is rotatably sleeved to the swing frequency control member (5E), a limiting member (5G) is installed on the swing frequency control member (5E), and the limiting member (5G) limits the swing width control member (5F) from moving away from the swing frequency control member (5E) in the axial direction.The inner periphery (N1) is recessed relative to the outer periphery (N2), and by performing positional limitation in cooperation with the limiting member (5G), the surfaces of the outer periphery (N2) and the limiting member (5G) are generally flattened, making the overall structure more dense and thin. To improve wear resistance, a wear-resistant spacer may be installed between the swing frequency control member (5E) and the swing width control member (5F).

[0029] The swing frequency control member (5E) is connected to transmit power to the swing frequency drive motor (5H) through the swing frequency power transmission mechanism (5J), and rotates around a set central axis upon receiving the drive. In this embodiment, the swing frequency power transmission mechanism (5J) is a duplicate gear, one end being a bias gear (or turbo) and the other end being a straight gear. The end of the binary bias gear (or turbo) of the duplicate gear meshes with a worm installed on the swing frequency drive motor (5H). It can be understood that the swing frequency power transmission mechanism (5J) can be configured to transmit power in a multi-stage gear manner, which is not described further here. The swing width control member (5F) is connected to the swing width drive motor (5I) through the swing width power transmission mechanism (5K), and the swing width control member (5F) is driven and rotated by the swing width drive motor (5I). In this embodiment, the swing width power transmission mechanism (5K) includes a double gear (M1) and a gear rack (M2). The center of the rack (M2) and the rotational center axis of the swing width control member (5F) coincide; the double gear (M1) has one end that is a bias gear (or turbo) and the other end that is a straight gear, wherein the end of the bias gear (or turbo) meshes with the worm of the motor shaft of the swing width drive motor (5I), and the end of the straight gear meshes with the gear rack (M2). It should be understood that, unlike the swing frequency control member (5E) and swing width control member (5F) of the present embodiment which are rotated by different motors, in other embodiments, both may be driven by the same motor, and the motor may be connected to transmit power to the swing frequency control member (5E) and the swing width control member (5F), respectively, through two power transmission mechanism paths.

[0030] The position sensing mechanism (5N) is used to detect the rotational displacement of the swing width control member (5F), and when the swing width control member (5F) rotates in the forward and reverse directions, the guide sliding groove (S) above it allows the center base (5D) to move in a reciprocating linear motion in the sliding groove (K). In this embodiment, the swing width control member (5F) is equipped with two trigger units (N3), and the position detection mechanism (5N) is a micro switch. When the swing width control member (5F) reaches a limit position through forward or reverse rotation, the trigger unit (N3) touches the micro switch to trigger an electrical signal. By determining whether the position detection mechanism (5N) is triggered, it is possible to detect whether the rotational position of the swing width control member (5F) is at a limit position. Accordingly, it is possible to indirectly detect whether the position of the center base (5D) is at a limit position within the sliding groove (K). When the center base (5D) is at a limit position within the sliding groove (K), the control circuit (not shown) of the massage movement controls the forward or reverse rotation of the motor, thereby ensuring that there is no risk of collision with the center base (5D) within the sliding groove (K). The micro switch can be replaced with a position detection mechanism such as a Hall sensor and an optocoupler sensor, which will not be described again here. As described above, regarding the detection of the position of the center base (5D) within the sliding groove (K), only whether it is in two limit positions can be determined. In order to detect the specific position of the center base (5D) within the sliding groove (K) more accurately, an encoding disk sensor assembly can be installed on the motor shaft of the swing width drive motor (5I) to detect the number of rotations of the motor, and furthermore, the specific displacement amount of the center base (5D) can be estimated by the gear rotation ratio.After an electrical signal is triggered in the position detection mechanism (5N), the center base (5D) is considered to be in the starting position, and by detecting the specific displacement amount of the center base (5D) through the aforementioned method, the position within the sliding groove (K) where the center base (5D) is located can be accurately determined, and through this, the relative position between the sliding coupling part (5D2) and the long hole groove (5B-1) can be determined. By controlling the relative position within the swing arm (5B) where the sliding coupling part (5D2) is located, the swing width of the first massage head can be accurately controlled, thereby making the range of motion of the massage head wider, that is, by adjusting as needed, the trajectory of the massage head can be enriched. In another embodiment, the encoding disc sensor assembly can be mounted on the swing width control member (5F) and can directly detect the number of rotations of the swing width control member (5F), and since this can realize the same function as the function mentioned above, it is not described again.

[0031] In combination with FIG. 15, in another embodiment of the massage movement of the present application, the inner ends (5B1) of a plurality of swing arms (5B) are stacked and all are rotatably connected to a swing frequency control member (5E) (all are rotatably sleeved to an eccentric lever (5L), and the eccentric lever (5L) is eccentrically connected to the swing frequency control member (5E), and the rotational center axis of the swing arms (5B) is eccentrically installed with respect to a first set center axis. The inner end (5B1) of a plurality of swing arms (5B) is installed to be bent relative to the other part (5B2), and the degree of bending of the inner end (5B1) of each swing arm (5B) in this embodiment is sequentially greater than the degree of bending of the other part (5B2), so that the other part (5B2) of each swing arm (5B) can be located on the same plane, and in FIG. 15, the cover (5O) mounted on the end of the eccentric lever (5L) is omitted, and the cover (5O) prevents the inner end (5B1) of each swing arm (5B) from detaching from the eccentric lever (5L). When FIG. 17 is combined, a second massage head (5Q) can be further installed on the cover (5O) on the basis of the solution of FIG. 15.

[0032] The above description is merely a specific embodiment of the present invention, and the scope of protection of the present invention is not limited thereto. Any modification or substitution that any person skilled in the art could readily conceive of within the technical scope of the present invention shall be included within the scope of protection of the present invention. Accordingly, the scope of protection of the present invention shall be based on the scope of protection of the claims.
